The router with IP address 172.16.11.112 has nonpreempt configured.F. The router with IP address 172.16.11.112 is using default HSRP priority.

Answer: ABD

Answer: BD

QUESTION 234In a switch stack environment, what is the total bidirectional traffic flow between two logical counter-rotating paths?

A. 16 GbpsB. 32 GbpsC. 64 GbpsD. 128 Gbps

Answer: B

QUESTION 235A network engineer configures port security and 802.1x on the same interface. Which option describes what this configuration allows?

A. It allows port security to secure the MAC address that 802.1x authenticates.B. It allows port security to secure the IP address that 802.1x authenticates.C. It allows 802.1x to secure the MAC address that port security authenticates.D. It allows 802.1x to secure the IP address that port security authenticates.

QUESTION 237What is the default amount by which the hot standby priority for the router is decremented or incremented when the interface goes down or comes back up?

A. 1B. 5C. 10D. 15

Answer: CExplanation:The standby track interface configuration command ties the router hot standby priority to the availability of its interfaces and is useful for tracking interfaces that are not configured for HSRP. When a tracked interface fails, the hot standby priority on the device on which tracking has been configured decreases by 10. If an interface is not tracked, its state changes do not affect the hot standby priority of the configured device. For each interface configured for hot standby, you can configure a separate list of interfaces to be tracked.http://www.cisco.com/en/US/docs/switches/lan/catalyst3550/software/release/12.1_19_ea1/configuration/guide/swhsrp.html

QUESTION 238What is the maximum number of virtual MAC addresses that GLBP allows per group?

A. 2B. 4C. 6D. 8

Answer: BExplanation:GLBP Virtual MAC Address AssignmentA GLBP group allows up to four virtual MAC addresses per group. The AVG is responsible for assigning the virtual MAC addresses to each member of the group.Other group members request a virtual MAC address after they discover the AVG through hello messages.Gateways are assigned the next MAC address in sequence. A virtual forwarder that is assigned a virtual MAC address by the AVG is known as a primary virtual forwarder. Other members of the GLBP group learn the virtual MAC addresses from hello messages. A virtual forwarder that has learned the virtual MAC address is referred to as a secondary virtual forwarder.Reference: http://www.cisco.com/en/US/docs/ios/12_2t/12_2t15/feature/guide/ft_glbp.html#wp1039651

QUESTION 239Which option is a benefit of using VSS?

A. reduces costB. simplifies configurationC. provides two independent supervisors with two different control planesD. removes the need for a First Hop Redundancy Protocol

Answer: DExplanation:First Hop Redundancy Protocols (FHRPs) such as VRRP and HSRP were designed to allow for a highly available first IP route hop for host systems.FHRPs allow two (or more) distinct routers to share a common IP address providing a redundant Layer-3 default gateway for end nodes. The VSS system creates a single logical router at Layer 3. This VSS routing instance fulfills this first-hop role without the need for a dedicated protocol. The VSS IP route is highly available due to MEC and the resiliency of the VSS system. VSS eliminates the need for FHRP at the aggregation layer of the data center.Reference: http://www.cisco.com/en/US/docs/solutions/Enterprise/Data_Center/vssdc_integrate.html

QUESTION 240Which statement about restrictions for multichassis LACP is true?

A. It is available only on a Cisco Catalyst 6500 Series chassis.B. It does not support 1Gb links.C. Converting a port channel to mLACP can cause a service disruption.D. It is not available in VSS.

Answer: CExplanation:When configuring mLACP for Server Access, follow these guidelines and restrictions:PFC3A mode does not support the mLACP for server access feature.VSS mode does not support the mLACP for server access feature.No more than 100 VLANs can be active on a switch configured as a PoA.mLACP does not support half-duplex links.mLACP does not support multiple neighbors.Converting a port channel to mLACP can cause a service disruption.The DHD system priority must be lower (higher numerically) than the PoA system priority.Reference: http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/mlacp_server_support.html

QUESTION 241What is the default value for the errdisable recovery interval in a Cisco switch?

A. LLDP-MED is an extension to LLDP that operates between endpoint devices and network devices.B. LLDP-MED is an extension to LLDP that operates only between network devices.C. LLDP-MED is an extension to LLDP that operates only between endpoint devices.D. LLDP-MED is an extension to LLDP that operates between routers that run BGP.

Answer: AExplanation:LLDP for Media Endpoint Devices (LLDP-MED) is an extension to LLDP that operates between endpoint devices such as IP phones and network devices such as switches. It specifically provides support for voice over IP (VoIP) applications and provides additional TLVs for capabilities discovery, network policy, Power over Ethernet, and inventory management.

QUESTION 243A switch has been configured with the vlan dot1q tag native command. Which statement describes what the switch does with untagged frames that it receive?

A. Untagged frames are forwarded via the default VLANB. It drops the untagged framesC. The trunked port is put in err-disable stateD. Untagged frames are forwarded via the native VLAN

A. When a new workstation connects to port F0/1B. When 61 MAC address are in the switchC. When 61 percent of the Address table capacity is usedD. When the switch loses power and rebootsE. When the phone previously on Fa0/2 is now connect to Fa0/5
